'Beauty and the Beast' Teaser Gives First Glimpse at Emma Watson as Belle

While the short clip doesn't give too much away, fans do get a first glimpse at Emma Watson's portrayal of Belle. "Look, a girl," a voice exclaims as the door to the mansion opens. "Yes, I can see it's a girl, you fool!" Cogsworth (Ian McKellan) replies.

Beauty and the Beast is the adaptation of the classic fairy tale about a monstrous prince and a young woman who fall in love. The film also stars Luke Evans as Gaston, Kevin Kline as Maurice, Josh Gad as Le Fou, Stanley Tucci as Cadenza and Emma Thompson as Mrs. Potts.

ET recently spoke to McGregor about how one goes about taking on the role of a talking candelabra. "I don't know if I'm meant to say, we are animated mainly. Then there's a sort of live action, a bit towards the end," he dished to ET. "I get to sing a great song, 'Be Our Guest,' the great number that Lumiere sings in the film."

The actor added that he was thrilled to work with such a talented cast. "It was great. We had Sir Ian McKellen and Emma Thompson, Stanley Tucci -- some great, great actors," he bragged. "It was fun to be part of that."
